Whether or not any of us has seen a drone, chances are increasing that a drone has seen one of us. Photographer Tomas van Houtryve, interested in "the changing nature of surveillance, personal privacy and war," got himself a drone and made it capable of taking and transmittiing high-resolution images from the sky.

The resulting photos, shot over U.S. skies, are part of van Houtryve's series Blue Sky Days. The project was inspired by a news report on an October 2012 drone strike in Pakistan, in which a 67-year-old woman was killed while picking okra outside of her home. At a Washington, D.C. conference with five legislators in attendance, the woman’s 13-year-old grandson said, “I no longer love blue skies. In fact I now prefer grey skies. The drones do not fly when the skies are grey.”

Van Houtryve intended to capture shots of settings and gatherings that could conceivably be considered targets in a foreign air strike. Included were weddings, funerals, prayer and exercise groups, prisons and oil fields. See more of Tomas van Houtryve's work at his website. Via Juxtapoz.
